Translate into German— It has sometimes been remarked that Prussia, and more particularly Berlin, has an unfair share of knights, but the explanation given is no doubt true-namely, that Berlin often attracts later in life the best men in every branch of learning, in whatever part of Germany they may have been born. It has also been objected that hardly any one, however distinguished he may be, is elected before he is past fifty; but this, too, can hardly be surprising, because it is only in recognition of original work and work of a permanent value, that these knights are chosen. 13.

A person wishing to ascertain the height of a tower stations himself in a horizontal plane through the base at a point at which the elevation of the top is 30°. On walking a distance a in a certain direction, he finds the elevation of the top is the same as before, and on walking a distance five-thirds of a, at right angles to his previous direction, he finds that the elevation of the top is 60°. Shew that the height of the tower is a ora. 12. Prove that if in measuring the three sides of a triangle a small error x be made in the side a, the consequent error in the diameter of the circumscribing circle will be x cosec A cot B cot C.

Prove that the square of the tangent from any point on a given circle to a second given circle varies as the perpendicular from that point upon the radical axis of the two circles. Find the locus of a point such that the tangents from it to two given circles may have a given ratio. |
